| Exemplary metered dose dispensers are disclosed herein. One exemplary embodiment includes a container and a one-dose dispenser secured to the container. The one-dose dispenser includes a dosing chamber; a shuttle member movable within the dosing chamber; an outlet valve located at an end of the dosing chamber and an outlet located downstream of the outlet valve. A liquid inlet is also included for allowing liquid to flow into the dosing chamber to an area between the shuttle member and the outlet valve. Pressurizing liquid in the container moves the shuttle member from a first position to a second position and dispenses the liquid in the dosing chamber; and when the shuttle member is in the second position, the shuttle member seals off the outlet valve. | ||||||

| The application describes liquid dosing devices of the kind in which flow to a front discharge opening (44) of a container is blocked after a controlled delay by a sliding piston (3) movable in a control chamber (2) mounted in a container neck behind the discharge opening (44). Movement of the piston (3) is governed by restricted flow through control openings (28) at the back of the control chamber (2). Restoration of the piston (3) after a dosing operation is assisted by providing a dump valve at the rear of the control chamber. For simplicity and ease of construction, as well as effective sealing operation, the dump valve member is a ball (6) retained in a cage (5). Another proposal provides a one-way valve in the outlet path, obviating the dump valve and enabling rapid recovery after a dosing operation when used with a resiliently squeezable container. | ||||||

| A liquid dosing device for a container comprises a dosing chamber having a front end and a back end. An outlet passage is located at the front end. A plunger is located in the dosing chamber, divides it in a front and a back space, and is moveable between a forward position in which the plunger closes off the outlet passage, and a backward position, in which the front space has a maximal volume. An inlet passage provides fluid communication between the front space and the container. A timer passage provides fluid communication between the container and the back space. A release passage, being greater than the timer passage, provides fluid communication between the back space and the container. A valve assembly at the release passage comprises a valve seat located at the back end of the dosing chamber and a membrane on a side of the valve seat facing away from the back space. The membrane is made of an elastic foil having a uniform thickness. It has a stationary portion that is fixed and at least one moveable flap which is connected to the stationary portion by a hinge portion. The flap is moved away from the valve seat in the open state and bears against the valve seat in the closed state of the valve assembly. The hinge portion is elastically flexed when the flap is moved away from the valve seat and is in a rest state when the flap bears against the seat. | ||||||

| A novel metering device (1) for dispensing a dose of a pressurized fluid is described. A dispensing valve body (3) is mounted in a fluid-tight manner to the lid (4) of a pressurized container (5), which circumvents a valve element (9). A valve delivery tube (10) is connected to the valve element (9). A chamber (13) surrounds the valve body (3), in which a piston (17) is reciprocable between an upper and a lower position, which define the dispensing dose. A clearance is provided between the piston (17) and the inner wall (23) of the chamber (13), such that pressurized fluid can flow into the chamber based on a pressure difference between the container (5) and the chamber (13), and the piston (17) is adapted to seal the valve body (3) when being in the upper position. | ||||||

| A fluid dispensing system provides a non-contact method of monitoring the change in the fluid volume over time. This approach avoids the use of probes or sensors that come into direct contact with the fluid to be dispensed. The system (1) comprises an apparatus comprising three chambers (10, 11, 14). The first chamber (10) has a fixed volume and contains a pressurized gas. A solenoid valve is used to control the flow of gas from the first chamber (10) into the second (11). The second chamber (11) is sealed so that the combined mass of air in the first (10) and second (11) chambers remains fixed. The third chamber (14) is adjacent to the second (11) and contains medication in the form of incompressible fluid that is to be administered to a human or animal subject via a suitable delivery port. | ||||||

| A dispensing closure for dispensing a flowable product from a squeeze-type product container includes a closure body having an upper deck, an exit orifice, and a skirt configured to attach to the product container. A measuring reservoir is received in engagement with a lower surface of the upper deck. The measuring reservoir is filled with a measured dose of flowable product through flow ports when the container is inverted. A piston valve is slidably movable within the measuring reservoir between an open position and a closed position. The piston valve is movable from the open position to the closed position to dispense the measured dose of product responsive to pressure within the container induced by squeezing. | ||||||

| A container used in daily life comprises a container main body, and a pressure channel composed of a pressure transmission channel, a removal channel and an outflow channel connected in series. The pressure channel, attached to a wall of the container main body, has one end in communication with the removal channel and the other end connectable to a pressurizing component provided externally. The pressure transmission channel transmits pressure exerted on the inside of the pressure transmission channel by the pressurizing component provided externally, via a pressure transmission medium inside the channel. A wall of the removal channel is provided with a one-way valve allowing the contents to flow into the pressure channel. The one-way valve opens at the bottom on the inside of the container main body. The outflow channel is used for flowing out the contents from the container and preventing the contents flowing back. | ||||||
